Definitions

  • This invention refers to a method and a device for the high sensitivity analysis of multiple analytes in biological samples.
  • the invention refers to a method and a device for the detection of complementary pairs of molecules, such as nucleic acid-nucleic acid (e.g. DNA-DNA, DNA-RNA, RNA-RNA) or protein-protein (e.g. antigen-antibody) pairs.
  • nucleic acid-nucleic acid e.g. DNA-DNA, DNA-RNA, RNA-RNA
  • protein-protein e.g. antigen-antibody
  • PCR Polymerase Chain Reaction
  • LCR Ligase Chain Reaction
  • Quantitative PCR which is based on the amplification of target DNA, is another common modification of PCR, but is only able to generate semi-quantitative data (number of copies of a DNA sequence in a sample) and can be affected by the presence of inhibitors and low copy number templates.
  • ELISA Enzyme-Linked Immunosorbent Assay
  • biochemistry is used to detect the presence of an antigen that is characteristic of a particular pathogenic organism, or to measure the concentration of antibodies in blood plasma (as in AIDS tests, for example).
  • This technique relies on specific antigen-antibody reactions that are made visible by various procedures.
  • many other ELISA-related techniques have been developed. One of them is the "Two-hybrid capture” technique, developed by Digene Corp. for the detection of human papilloma virus (HPV), which is able to detect RNA:DNA hybrids using an amplified chemiluminescent signal.
  • HPV human papilloma virus
  • a DNA microarray is a collection of microscopic DNA probes arrayed on a solid surface, such as glass or plastic, that bind to chemically suitable, complementary targets that have been previously amplified and tagged with a fluorescent molecule, which permits detection of fluorescent signals generated upon hybridization.
  • These techniques therefore permit multiplexing, but require prior target DNA amplification to ensure optimal sensitivity, as in the case of RT-PCR-amplified mRNA detection. As such, they are affected by the aforementioned drawbacks of PCR.
  • Microarrays also require very expensive scanners and sophisticated detection systems, which consist of specific focalized lasers that reveal every single micro-spot. Moreover, they are not easily automated and are therefore not very useful in diagnostics. In addition to this, they are also affected by the aforementioned limitations of fluorescent detection.
  • a conductivity-based DNA detection method utilizing oligonucleotide-functionalized Au nanoparticles is described by Park et al. in "Array-Based Electrical Detection of DNA with Nanoparticles Probes", Science, vol. 295, pages 1503-1506 .
  • W003/095973A2 discloses an analyte detection method based on the use of Raman labelled nanoparticles that can be activate to provide SERS effect.
  • a DNA detection method based on latex microsphere and gold nanoparticles is described by Reynolds III et al. in "A gold nanoparticle/latex microsphere-based colorimetric oligonucleotide detection method", Pure Appl. Chem., Vol. 72, Nos. 1-2, pp. 229-235, 2000 .
  • Gold and latex probes are linked together by the target DNA strand, generating a white-to red color change in a size-selective membrane through which excess or nonhybridized gold particles are separated from latex indicator probes.
  • the aim of this invention is to deliver an analytical biotechnology technique that is able to carry out detection of complementary pairs of molecules, such as nucleic acid-nucleic acid (DNA-DNA, DNA-RNA, RNA-RNA) or protein-protein pairs, without the drawbacks of other techniques.
  • complementary pairs of molecules such as nucleic acid-nucleic acid (DNA-DNA, DNA-RNA, RNA-RNA) or protein-protein pairs
  • the object of the invention is to provide a method and a device for the simultaneous and quantitative detection of different subtypes (multiplexing) of a given biological target system (virus, genetic mutations, etc.).
  • the aforementioned aims are achieved using a method and a device that exploits the interaction of non-biological nanoparticles with biological structures (such as nucleic acids and proteins) to determine dimensional increases, thereby permitting the detection of a biological target (virus, genetic mutations, etc.).
  • biological structures such as nucleic acids and proteins
  • the proposed method and device make use of a microarray architecture of nanoparticles linked to molecular probes or specific antibodies, which are adsorbed onto a solid surface and preferably arranged in a monolayer.
  • the aim of the system is to specifically detect complementary pairs of molecules, such as protein-protein pairs (e.g. antigen-antibody complexes) and DNA-DNA or DNA-RNA pairs (e.g. probe-target complexes).
  • protein-protein pairs e.g. antigen-antibody complexes
  • DNA-DNA or DNA-RNA pairs e.g. probe-target complexes
  • focalized laser sources coupled to a system of photosensors can preferably be used.
  • Various detection strategies can then be exploited, such as image analysis or light scattering.
  • binding to two other components Y,Z of the complementary element of the other pair is determined (in the illustrated example, two elements complementary to two different terminal portions of the target), one attached to a nanoparticle N and the other to a solid support S.
  • latex nanoparticles N that are monodispersed in the suspension under test, specifically bind to the target X through complementary molecular probes Y that are attached to the nanoparticles.
  • These nanoparticle-probe-target complexes diffuse by Brownian motion from the liquid suspension to the solid-liquid interface and dock onto the solid surface S (e.g. one of the internal surfaces of the tube containing the suspension) as a monolayer, resulting in the target X binding to other specific molecular probes Z (which are complementary to other portions of the target), that are also adsorbed onto the solid surface.
  • the proposed method guarantees rigidity and reliability, as well as rapid analysis and automation. Moreover, less time and money will be required to train personnel, compared to previous techniques.
  • the method and the device according to the present invention enable two crucial aims in the medical diagnostic field to be fulfilled.
  • the first of these is signal enhancement, in addition to better use of the solid space and selective concentration of the molecule to be analysed in a two-dimensional state, and secondly, the ability to carry out more simultaneous tests, in the same reactor and on the same sample (multiplexing), resulting in a considerable saving of time, money and biological material.
  • this last feature is especially advantageous when it comes to detecting genetic mutations in human samples and can also be used to genotype viruses that are dangerous to humans.
  • the genome (G1-G4) of the various HPV subtypes is the target to be detected.
  • the probes (C) attached to the nanoparticles (N) are DNA probes that are complementary to the conserved regions of the HPV genome (and are therefore able to detect any HPV subtype), whereas the probes (V1-V4) attached to the solid support (S) are DNA probes that are complementary to the variable regions of the HPV genome (therefore, they can specifically detect a particular HPV subtype). As a consequence, this permits the spatial detection of various subtypes (multiplexing).
  • the system foresees the use of a plastic container (e.g. a tube), on one of whose internal surfaces (S) an area of approximately 1 cm 2 is selected and sub-divided into different cells (1-4).
  • a plastic container e.g. a tube
  • S internal surfaces
  • V1-V4 oligonucleotide
  • V1-V4 corresponding to a particular DNA probe that is complementary to the variable part of the genome of a specific HPV genotype
  • the biological sample is added to the tube so that qualitative and quantitative measurements of HPV can be made.
  • a specific target e.g. G1
  • binding occurs between the target and a nanoparticle (N), through its conserved DNA portion (C), and with portion (I) of the internal surface (S) of the tube, through its variable DNA portion (V1), resulting in docking of the nanoparticles onto the internal surface of the tube ( Fig. 3 ).
